Match the tank to the space. 100–200 ml is a bedside or desk unit and will run most of an evening. 300–500 ml suits a living room. For an open-plan space or a hallway, a waterless or tower unit carries much further than any water-based diffuser, because it atomises the oil rather than riding it on mist.

An ultrasonic diffuser mixes oil into water and lifts it as a cool mist, which adds a little humidity and gives a soft, close scent. A waterless (nebulising or cold-air) unit atomises neat oil, uses no water, and throws scent much further. Waterless units use oil faster and cost more to run; ultrasonic units need cleaning more often.

Rinse the tank and wipe the ultrasonic plate every week if you use it daily, and run a cycle of water with a little white vinegar every month. Oil residue on the plate is the single most common reason a diffuser stops misting.
